OP, please remember that when some people are sick, they start exhibiting emotions and behaviors they would not normally show. Some patients become clingy, depressed, angry and anxious. Some patients may even regress to childhood. Since nurses are at the bedside, patients will transfer all their negative and positive emotions to the nurses. Nursing tasks may be professional, but there are some component of personal interaction in the daily dealings with patients. Without this personal component, nurses will not be able to care for their patients holistically.
